What are Microservices and How to Implement Them?
INTRODUCTION
Microservices are increasingly useful in the development world. As developers, today work to create larger and more complex applications. Certainly, these large applications are better developed and also manageable as a combination of smaller services that work together for more extensive, application-wide functionality. You can learn to work better on architecture with Microservices Training Institute in Noida for better guidance. A descriptive training approach can never go wrong in the process of learning something this important.
What Are Microservices Architecture?
Microservices architecture treats each function of an application as an independent service. Which you can alter, update, or take down without affecting the rest of the application. Basically, Applications were earlier built as monolithic pieces of software. Adding new features needs reconfiguring and updating everything from the process and further communications to security within the application. Traditional monolithic applications however have long lifecycles, and continuous updates, which usually affect the entire application. This costly and difficult process delays advancements and updates in enterprise application development
The Microservices architecture was designed to solve this problem. You can create all services individually and deploy them separately from one another. This architectural style allows scaling services on specific business needs. You can even change certain services, without affecting other parts of the application.
With Microservices architecture you can do the following things;
• You can break the Application into modular, loosely coupled components
• Distributing Applications across clouds and data centers
• Adding new features only requires updates on those individual microservices
How to implement the microservice architecture
Whether you’re starting from scratch or rebuilding an existing monolithic application, there are many things you need to pay attention to when implementing the microservice architecture.
• Follow Conway’s law when structuring your application Conway’s law is a well-known principle for the development management of software. This is usually applied as a thumb rule when organizing microservice teams and structuring microservice applications. If there are communication issues within the organization, like two teams working on overlapping goals. You can easily end up with several smaller monolithic architectures connecting each other via APIs, instead of single-responsibility microservices
• Avoid ending up with accidental monoliths When software development teams try to split up an existing monolithic application into microservices, they however unintentionally create accidental monoliths. Not considering Conway’s Law can be one of the reasons, but you can run into other architectural issues when refactoring your code base. This situation can arise when
• A microservice exhibits more than one purpose
• Improper separation of data.
• The messaging system includes communication logic to move into the microservices
However, to avoid creating smaller monoliths instead of microservices, it’s better to move toward the new architectural style in smaller steps.
• Refactor your monolithic application with service objects
One way to gradually refactor an existing monolithic application into microservices is by developing service objects and identifying the data that each object inputs and outputs.
Service objects are objects that basically execute one single business action. They certainly don’t include any data but only perform the operations.
• Design smart endpoints and dumb pipes
The concept of smart endpoints – dumb pipes deliver the additional complexity of microservice applications. Which basically comes from the messaging mechanism that connects the individual services. An elaborate microservice architecture keeps the messaging system as simple as possible and avoids smart pipes. Because these solutions create more or less centralized systems, which can further lead to accidental monoliths.
CONCLUSION
The microservice architecture is most suitable for large-scale applications made by different teams and running in the cloud, whereas smaller apps are often better off with a monolithic code base. Container platforms, like DevOps practices, and cloud computing can help a lot in adopting the microservices architecture.
